Planethi yehango ndiyo inolema kwazo kakale ndiyo whulu kupinda amwe maplaneti, kakale ndiyo inamabhgwe manjinji mumaplanethi mana emabhgwe.

Pahhe kweplanethi yehango (lithosphere) yakapalalanyiwha ikabe mapleyiti manjinji anoyenda pasi kwemakole alimiliyoni. 29% yeplanethi yehango, mitunhu inabugalo gwebanhu. Kukoti 71% yasala ihhele vula, kwazo kwazo maOsheni, madamu makulu, njizi ndevula yakatjenha , kose ikoku kodangwa kuyi hhadrosifiye. Bunji gweplanethi yehango mumitunhu yemaphola kuhhele ayisi, kuhanganisila Antarctic ice sheet nde damu gulu le ayisi leku Arctic ice pack. Mkati kwePlanethi yehango kogala kunatshipi yebhgwe , vula yapahhe inothama kuti planethi yehango inamatile ndebhepe linondisa ma pleyiti anobumba planethi yehango.

Mumakole anoswika mabhiliyoni mahhanhu okutanga kwebumbiwha kweplanethi yehango ntolo, butjil gwakaguli mudzioshiyeni , kukoti ndoyenda kwelubaka kukobe ndebutjilo pehhugwi kweplanethi ndapasi, kukothama kuti kuzwagwe kwakasiyana kunotjila. Bupaki gwezwidiyo zwehango golakidza kuti butjilo gungabe gwakatanga kumakole angaswika 4.1 bhiliyoni akapinda. Milikila ipapo bulefu gomilika muplanethi yehango ubva kuhhuba, kwakabumbiwa, ndebumilo gwehango kobvumila kuti kube ndebutjilo kakale gupfumile. Mumabvilo ebutjilo gumuplanethi yehango, kose kunopfema kosiyana kakale kondidzana ndebumilo gwako. Kungapinda 99% yezwinhu zwakazwitjila zwisitjipo muplanethi yehango. Kokumbuligwa kuti zwinhu zwinotjila muplanethi yehango nhasi zwakasiyana kwazo, zwimwe azwitozimbgwa. Bengapinda makole ali 7.7 bhiliyoni banhu banotjila muplanethi yehango kakale butjilo gwabo gwakabhatilila mubhayosifiye ndekwakabumbiwa ndeNdzimu.
